不定式是英语语法的一个重要的版块,今天,小编为同学们准备了相关的不定式语法体系下的不定式的完成进行体的使用规则,一起来看看吧! 一、动词不定式的完成进行体表示不定式动作发生在谓语动作之前,并一直在进行着。其结构与不定式的完成体类似。如: He is said to have been translating Luxun's works into English . 据说他一直把鲁迅的著作译成英文。(现仍然在译) She seems to have been teaching in that school for fifteen years . 她似乎已经在那所学校教了15年书了。(仍在教,强调继续教) The kind-hearted millionaire is very happy to have been helping the poor . 那个善良的富翁一直在帮助穷人,并为此感到非常高兴。(仍在帮) We supposed to have been living here till our children grew up . 我们原以为可以在这一直住下去,直到我们的孩子长大。(但我们得搬家了) 二、动词不定式完成体的被动式 当主语与不定式动词有被动关系,且不定式所表示的动作又先于谓语动词动作发生时,动词不定式就要用完成体的被式。如: The book is said to have been translated into many languages . 据说这本书被译成很多种语言。 The oranges were thought to have all been sold out . 人们认为桔子已经全部卖完。 He is very sad to have lost four bikes in less than one year . 他因不到一年就丢了4部自行车而感到很伤心。
